i'll also hopefully be getting 2 Raptors somewhen down the line as well.
don't want to touch Crossfire just yet, as i know there is only one board out there and it has got some bad reviews. so crossfire isn't on the list.
Read the recent Asus A8R-MVP review. Might be a good option when it hits the streets...I linked the review in another thread in here. Three current options: Epox 9NPA+ Ultra, Abit AN8 Ultra and Chaintech VNF4 Ultra. Look at price/features to make your decision...
I read the A8R-MVP is a reasonably-priced, full-featured board that is not really missing any important features. Instead of the limitations of SB450, it has the advantages of ULi M1575. And this value-priced board produced the highest overclocks that we have ever seen with our OCZ Rev.2 Platinum memory and our 4000+ CPU.
If you dont care about overclocking go with the Chaintech VNF4. You just cant beat it for the money....$69 bucks at newegg....I just cant justify spending 40% to 100% more for another mobo that has the exact same chipset / performance.
